Basically, we would already be done here, but now each user would only have access to their own home directory (e.g. /home/pi ). Therefore we create a new user. To do this, we first change the directory.

cd /etc/proftpd/

In the next command please change the name (tutorials) and the path ( /var/www ) where you should see when you go to the server with ftp

sudo ftpasswd --passwd  --name tutorials --gid 33 --uid 33 --home /var/www/ --shell /bin/false

Now just enter the password and confirm. If you want to change the user's password at a later date, simply switch back to the directory and run the command again.

In order to unlock the virtual user, we edit the configuration file

sudo nano /etc/proftpd/proftpd.conf

und fügen folgenden Code am Ende ein: 

DefaultRoot ~

AuthOrder mod_auth_file.c  mod_auth_unix.c

AuthUserFile /etc/proftpd/ftpd.passwd

AuthPAM off

RequireValidShell off

With CTRL + O and CTRL + X we save and exit the editor.

Last but not least, we restart the server and try it out

sudo /etc/init.d/proftpd restart

You may still not be able to log in because the corresponding rights are missing, we set them as well

sudo chown -R pi:www-data -R /var/www/html

chmod 777 -R /var/www/html
